SUN-POWER WATER-HEATER.

Specification of Letters Patent.

Application led September 19, 1913. Serial No. 790,705.

'Be it known that I, ALFRED C. THmNG, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented new and useful [mprm'ements in Sun-PowerlVater-Heaters. of which the following is a. Specification,

This invention is' an improved sun-power Water heater Jtor concentratingthe rays ot the sun and ntilizing'the same. to heat water, the objeet otthe invention being to provide an improved apparatus of this character.

which is cheap and simple in construction` is strong and durable and theparts of Whiclr may be readily removed.

The invention consists in the construction, combination and arrangementof devices hereinafter described and claimed.

ln the accompanying drawings: Figure l is a plan ofa sun-power waterheater constructed Yin accordance with my invention with a portion otlthe glass top plate removed and a portion ot the wall -oif the Casingshown in section. Fig. 2 is a vertical sectional view of the same on theplane indicated by the line Q-2 of Fig. l.

The casinay l is here shown as rectangular and comprising` a bottom 2and walls 3. A. water tank 4 which is smaller than the casing, is.arranged therein and spaced from the Wall and bottom thereof, .thespace between the tank and the casing being filled with non-conductingVmaterial as at 5. 'At opposite sideS of the tank are inlet and ont,-letpipes G and 7. The tank is provided with a cover S which has'circular openings 9 and under the `said openings are semi-sphericalradiating' casings 10 which are made of inf-.tal and in practice arepreferably Welded to the cover 8.

lienees ll which are here shown as spherical are arranged to be placedinthe 'openings 9 and are provided with peripheral flanges 1Q which bearon the top plate or cover 8 ot' the tank and serxo to .support thelenses Cir so that their upper halves project above the plate S and.their lower halves extend down into and are spaced from thc radiatingcasiueje l0 The water in the tank surrounds the :mid radiatingv casingsand is directly in contact with it as shown. The flanges l2 desired. Theouter casing 1 is provided Wltn a glass top 13. A flange lt is arrangedaronndthe inner side ofthe wall olf' the rasing l and bears on the top Sot the water tank and also covers the terial 5.

In the operating of my water heater the insolating,r navrays of the snnare focused by the lenses liand caused to highly heat the radiatingcasings l0 and the latter, beingin direct contact with the water, heatsthe water will be understood. The non-conducting packing retains'theheat and minimizes the loss ot' Patented Apr. 14, 'l 91.4.

enable the lenses to be readily removed when said openings and providedwith supprn'ting,r j

flanges which bear on the tank cover.

2frl"he herein described snn-power water the walls and bottom thereof`non-conducting material in the space between the casing and the tank, acover for thetank haring circular openings therein and semi-spherical.radiating ozlsings on the under side of the cover, under said openingsand arranged in the 'water in the tank. spherical lenses having theirlower portions arranged in said radiating casings, 'said lenses havingsupporting fianges which bear on the tank cover and a glass top ontheouter easing.

In testimony whereof atlizf: my signature in presence of two Witnesses.
